Contact lenses come in a variety of shapes and styles to suit the range of needs for individual patients. What this means is that there is almost certainly a type of contact lens that will both feel comfortable for you and improve your vision.

Some types of contact lenses are known as speciality lenses. This is because they are designed specifically to overcome some eye issues which may prevent a patient from wearing the most common and generic styles of contact lenses. In fact, speciality contact lenses have transformed the vision options of many patients who would otherwise have only had the choice between wearing glasses or undergoing laser vision correction. There are numerous types of speciality contact lens, including scleral lenses.
 

What are scleral lenses?

Scleral contact lenses get their name from the fact that, unlike regular contacts, they vault over the entire corneal surface and rest on the white part of the eye, which is called the sclera. This makes them larger than standard contacts, which in turn provides a variety of benefits. Their size makes them easier to handle and more stable when on the eye, which in turn provides the patient with sharper and more reliable vision. They are also less likely to become dislodged and come out. 

Scleral contact lenses are also gas permeable, which means that oxygen can pass right through them and reach the surface of the eyes. This is important for comfort, particularly for patients who experience dry eyes. The gap that is created between the back of the contact lens and the front surface of the eye can also trap tear film, acting as a fluid reservoir which will keep the eyes moist and healthy. 
 

Types of scleral lenses

Within scleral lenses there are several different sizes to choose between. These are based on where the lenses meet the surface of the eye and are as follows:

• Full scleral lenses: the largest type, they provide the greatest amount of clearance between the cornea and lens and rest on the outer sclera. 

• Mini scleral lenses: the mid-size variety, make contact with the eye on the anterior sclera. 

• Semi-scleral lenses: although larger than conventional lenses, they are not huge, and the edge of the contact lens rests on the junction between the cornea and the sclera. 
   

Your scleral lens provider will be able to make a recommendation as to the correct size for you, which will be based on your individual requirements. 

Over the years, contact lenses have evolved. A new product called MiSight is giving children a new and improved option. MiSight lenses effectively treat myopia, otherwise known as nearsightedness.
 

Myopia

Myopia is the medical term used for nearsightedness. Of all correctable visual impairments, myopia ranks number one. With this condition, the eye grows too long from the front to the back. As a result, images don’t focus on the retina. Instead, they focus at the front of it. With this refractive error, individuals can see things up close without any problem but everything at a distance appears blurry. Over time, myopia in children typically worsens. This refractive error puts them at risk of developing other problems. For example, they’re more prone to having premature cataracts and detached retinas as an adult.

To treat this condition, most opt for prescription eyeglasses or contacts. Although MiSight Lenses work similarly to conventional lenses, they’re unique.
 

Benefits of MiSight Lenses

These contacts slow the progression of myopia in children between the ages of eight and 12. Even more exciting, they slow the progression by as much as 59%. For instance, if an ophthalmologist or optometrist diagnoses a child with nearsightedness and predicts a diopter of -8.00, MiSight contact lenses can reduce that to about -3.50.

As the only contact lens on the market capable of doing this, the Food and Drug Administration (FDA) fully approved them in 2019.

Another benefit of wearing MiSight contacts over traditional lenses is their soft lens. Especially for younger wearers, they provide optimal comfort.

Also, an individual only wears them once before discarding them. It’s important to note that these contacts aren’t made for overnight wear. For that reason, users need to remove them from the eyes and discard them at the end of each day.

The eye is a very delicate and fragile part of the body. According to one study on distance vision, about 188.5 million individuals are said to suffer from mild vision impairment, 217 million individuals suffer from moderate and severe impairment while 36 million individuals are blind. For near vision impairment, there are about 826 million individuals suffering. In all, there are about 1.3 billion people living with one of these impairments.

While a lot of people are aware that the eyes are an integral part of the body system, most of them do not pay very close attention to taking care of their eyes and are, in essence, taking it for granted. As the saying goes, “You don't know what you have until it's gone," and therefore, we have decided to take the necessary steps to provide you with information on how to best to take care of your eyesight.
 

Below are ways to keep your eyes safe:

1. Eat Healthy

Eating a healthy diet is a very integral part of keeping the eyes healthy. Nutrients like lutein, vitamins E and C, omega-3 fatty acids, and zinc may help in preventing eye-related problems like cataracts and macular degeneration. These nutrients can be found in vegetables like collards, kale, spinach, fish like tuna, salmon, and halibut, as well as in beans, nuts, eggs, oranges, pork, and oysters.

Besides eating meals rich in nutrients, it is equally important to eat a well-balanced diet. Obesity can cause diabetes and other medical conditions, leading to blindness or glaucoma. Obesity is also regarded as the chief cause of blindness across the globe which should raise a red flag to watch your weight. You can always visit your doctor to get help with drafting a healthy eating plan.
 

2. Know your family's medical history

Eye issues are usually hereditary which is why it is important to collect a family history on any diseases that may affect eye health and then report them to your eye doctor. This will help to determine your chances of any future eye conditions as well as come up with an action plan for future eye exams.
 

3. Avoid Smoking

Smoking, in general, is harmful to your overall health. In regards to your eyes, it can cause macular degeneration, destroy the optic nerve, and cause cataracts. It can even lead to vision loss. Quitting smoking if you already smoke, or better yet, not even starting, will be extremely beneficial to your overall health and wellness.
 

4. Wear Sunglasses

Sunglasses are more than just fashion accessories, they are vital in protecting the eyes from ultraviolet rays emitted from the sun. UV rays can cause macular degeneration and even cataracts which is why it is important to wear sunglasses that protect against 99% -100% of UV rays.
 

5. Obey workplace safety precautions

It is important we wear protective eye gears when engaging in sporting activities or jobs that could be harmful to the eyes. Such eyewear includes safety goggles, glasses, and helmets. Most of these protectors are from polycarbonates, which is a much stronger material than plastic.
 

6. Rest your eyes

Just like our bodies, the eyes also need rest to perform optimally. Depriving yourself of adequate sleep and rest can have an adverse effect on the eyes. During the use of the computer, remember to rest the eyes for at least 20 seconds after every 20 minutes by looking away from the screen. Doing this will reduce eye strain.
 

7. Visit your eye doctor regularly

Getting regular eye exams is one of the most important things you can do for your eye health. Conditions like glaucoma are much easier to treat if they are discovered early so don’t stay far from your doctor. 

What Is Myopia?

Myopia (or nearsightedness) is so common that nearly 50% of North Americans will have myopia by 2030. Myopia happens when the eye grows too fast, too long, and gets weaker. You may know it as blurry vision far away. At our practice, we specialize in pediatric eye care and treat myopia seriously.

Myopia can develop as young as age 3, and it often gets worse as children grow. Parents may not see signs that their child has myopia, such as squinting or having to sit up close to the television or computer screen to see clearly. Children often don’t realize their vision is blurry.

The heavy use of digital devices is not going away and certainly is not helping things. It is important to have your child take breaks that are at least 5 minutes long, at least once an hour. Children should also spend at least 90 minutes outside a day.

The younger your child, the faster their myopia tends to progress. Early and regular pediatric eye exams are essential for detecting myopia as soon as possible. Treating it early can help slow its progression and reduce the risk of serious eye health issues later in life.
 

Myopia Can Affect More Than Just Your Eyes

Myopia can affect your child’s ability to perform well in school, sports, performing arts, and other activities that require clear vision. Controlling myopia progression will free them up to be at their best.

If you believe that your child may have myopia, contact our office to schedule a pediatric eye exam - this is the best first step to take.

Seasonal allergies is a medical condition similar to other forms of allergies that occur when the body's immune system reacts to an external material in the environment during seasonal periods when plants and trees are pollinating. Seasonal allergies have a tremendous effect on millions of individuals annually causing a negative effect on eyesight. Seasonal eye allergies cause the eyes to become itchy, watery and red which in medical terms is referred to as allergic conjunctivitis. There are many allergens that can make our eyes go itchy and very red including dust, pollen, and smoke. These allergens, however, vary from one person to another. For example, while dust can cause itchy eyes for me, it might not be the same for you as it all depends on our immune system and the way it reacts against such substances.

When something is regarded as a dangerous substance by the eye, a chemical response is elicited to fight against the allergen which is what leads to the itchiness, redness, and soreness in the eyes. These reactions are usually a result of a change in seasons, mostly occurring in the spring when plants and trees are pollinating and during the fall when the ragweed plants are pollinating.
 

Seasonal Allergies Effect on the Eyes

As we mentioned earlier, allergens affect people differently, but there are general ways in which everyone reacts. You would know an individual is suffering from allergies through the following symptoms.

• Teary eyes - Since the eyes perceive substances like dust, smoke, pollens as harmful to the normal conditioning of the eyes, there is an automatic release of water in order to clean the eyes which is more of a defense mechanism against these foreign items.

• Swollen eyes - After the entry of these foreign items, it is very natural to feel itchy and want to scratch the affected eyes. During the scratching, the skin covering the eyes would become swollen due to continuous friction.

• Dry eyes - Dry eyes occur most times during winter seasons, not because of allergens like dust or pollen, but whenever there is extreme cold or snow. This causes the eyes to become dry which leads to soreness and redness.

• Itchy Eyes - Allergens are carried by air and could end up in your eyes at any time. A reaction to these allergens would cause your eyes to feel irritated from the inside and would create the urge to then scratch your eyes in an attempt to provide some relief.

• Red Eyes - Redness of the eyes is usually accompanied by other symptoms such as itchy eyes which cause the eyes to become swollen and very red. There are also capillaries inside the eyes that can become red whenever one is faced with an allergy.
